Half life period of decomposition of a liquid ‘A’ by irreversible first order reaction is 12 minutes. The time required for 75% conversion of ‘A’ is _____________ minutes?
Correct answer: B
Explanation
For a first-order reaction, the time for 75% conversion is $t = -2.303 imes (1/0.75) imes t_{1/2}$. This equals 24 minutes.
